Hey Folks,
I've got some old (like 2-3 years in some cases) mason jars with small yeast cakes in my fridge (I harvest off the starter when I'm making one -- usually pour 500ml into a sanitized jar and put it in the fridge for the next starter). Assuming there is no visible weirdness in the jar, and If I get one of these guys going on the stir plate and there is activity, would you assume it was ok? Are there any indicators one can get at the starter stage that would point to a bad yeast?
Obv. I'd prefer to not spoil a 5 gal batch of beer, but it also seems a shame to be replacing a bunch of different liquid yeasts for $$$ if I don't need to.
Anyone had experience with this?
